HYDRATOR. 1

Application filed April 26, 1915. Serial No'. 24,173.

To all whom t may concern.'

Be it known that I, JOHN C. SCHAFFER, a citizen of the United States of America, residing at Tifiin, Seneca county, State of Ohio,' have invented new and useful Hydrators, of 'which the following is a specification. f

This invention relates to agitation of material,` particularly material Aor materials with a liquid or liquids for .producing a homogeneous mass or product.

This invention has utility in hydrating apparatus, as in hydrating lime.

l Referring tothe drawings: j

Figure 1 is a side elevation, with parts brokenaway of an embodiment of the-invention in a lime hydrating apparatus, in which one device for material supply and one device for liquid supply suffices;

Fig. 2 is asection on the line II-ll, Fig. 1,Y with a portion of the platform'broken away;

Fig. 3 'is a section on the line IIL-III, Fig. 1, with a portion of vthe platform broken :'away;

Fig. 4 is a detail view of a ing to a movable arm; Y

Fig. 5 is a section on the line VI-VI, Fig. 5; and

y' Fig.` 6 .is a fragmentary detail of a plow mounting for a stationary arm.

The driving shaft 1 has mounted thereon l the pulley 2 connected by the belt 3 to drive the pulley 4 on the shaft 5 carrying thepinion 6 in mesh with ythe speed reducing gear 7 on the'shaft 8 carrying the bevel pinion 9 coacting with the bevel gear 10 on the upright shaft 11 central of the agitator housing yor cylinder 12 rising to terminate in the stack 13. h

The shaft 11 has fast therewith series of radiating arms -14 sustaining thereon the movable `or rotating platforms 15. Intermediate each pair of movable platforms 15 is a stationary platform 16 sustained by the stationary arms 17 mounted in the housing plow mounti v12. A further set of Stationary arms 17 is provided above the uppermost movable platform 15. v f

Detachably mounted byb'olts 18 to the fixed .arms 17 are Ythesockets19 in which may' beadjusted by set screws 20 the stems 21` for` the stationary plows 22. For convenient positive angular anchoring of the plows 22, the stems 21 may be of polygonal or octagonal form. j f

On the movable 'arms 14, there are seats which may have shallow retaining lips 23 adjacent the upper ends, land plates 24,125, may belocked in position by thek bolts 26 for completing sockets for theplow stems 21, vertically adjusted in said sockets by the set screws 20, while singularly-adjusted by the octagonal setting of the stems in the sockets. j j s The driving shaft 1 mayrhave mounted thereon the pulley 28'connected by thebelt 29 to the pulley'30v on the shaft 31 having the eccentric 32 provided with connecting ,rod 33 for rocking vthe lcrank arm 34 with shaft 35 having-the agitator arms -36 for loosening thev bulk' material in' the hopper or supply bin 37.

Fast on the shaft 31 is the belt pulley 38 for driving the belt 39 extending overfthe 4idler pulley 40. This belt 39 is sustained by idlers 41to form the bottom of the'hopper 37, while in traveling therefrom it is counterbalanced by the movable idlerV 42 carried by the lever 43 mounted in the fulcrum 44 on the frame 45. may be adjusted by counterweights l46. Connected to the lever 43 is'the link 47v eX- tending to the lever 48having the rod 49 connected to the gate 50 for shifting this slide or gate 50 toward or from the belt or conveyer 39 to automatically maintain the weight of material along this way of the supply device constant. The lever 48 has the fulcrum bearing 51.l Fast with thele- This lever 43' Patented May 14, 191s.

ver 48 isV the indicator arrow 52 movablel justablewrist pin 55 for varying the travel of the connecting rod 56 from a maximum to zero throw in reciprocatingthrough the arm 57 the piston rod 58 in the pump cylinder 59, carried by the brackets 60,61 on'the frame 45. Accordingly liquid* from the Y supply line 62 is handled `by the pump, ronly when the conveyeris running, and. in a deflnite ratio so adjusted as tothe conveyer,

for delivery of the liquid through the valved discharge line 68 and spray 64 and through the independently valved discharge line 65 and spray 66, while the determined and adjusted self regulating supply of material from the supply device is fed by the chute 67 central of the upper rotary platform 15 to be worked outwardly thereover by the stationary angularly disposed material progressing means or plows 22, as initially mixed with the spray from the pipe 64, while in its discharge over the outer edge of the platform 15 having clearance as to the housing 12, the vspray line 66 is further edective. From this point .the material is 'advanced inward -by zthe traveling plows 22 fon the arms 14 sustaining the 4uppermost rotary platform 15, until this material ron the uppermost Astai'fiona-ry yplatform 16 is discharged ythrough the central opening lhaving clearance as to the v shaft 11, and reaches the second .rotary platform l5.

In the handling of some materials, as

quick lime for hydration or slaking, it is ldesirable to nicely regulate the flow rate, even `to the 'extent of `retalrdin'g the progress, as Vby reversely arranged plows, as .plow 68, Fig. i3. Further in the mixing, some ma- -terials fully treated Imay work up and move more freely, and .providing a flange or lip l69 on the movable platforms 115 and lip 70 on the `stationary platforms 16, adjacent the clearance fall areas, maintain a loading of the :platforms for thorough agitation and mixing of lumpy particles into a uniform fully hydrated state of fine loose material.

The rate of running volume I'of material as well :as extent of the platforms and their number may :all be factors entering into the lcapacity of itheplant, while the various adjustments permit regulations vand automatic control for handling widely varying commodities. With `materials to be hydrated lsuch as lime, and lime and magnesia, heat changes occur, and collar 71, vspaced from the :shaft 11, permits air supply over :the lower platforms to rise and portions thereof may Ybe drawn off through the ducts 72, whilethe regulation of lsuch drawing off may be nicely lcontrolled by the dampers 73. In many instances `it 'is desirable to allow some of the heated air to pass over the agitated material on the upper platforms and :be discharged through the main stack 13.

Conveniently disposedV as to the various platforms :are access doors 74, andinspectionopenings 75, the former allowing of admission for V:plow setting, adjustment and upkeep, while the 'latter permit observation for checking up proper stage treatment of the material being handled.

As the .rotating platforms 15 yextend inward beyond the `material fall openings `central Afof the stationary platforms 16 and the the Acollar v7-1 passing over the mixed and slaked lime, dries this stock thoroughly while agitated on the platforms, as well as while falling between the lower latforms on its way to the discharge chute 9. Control of this fdrfyin-g air may be had hy allowing considerable volume for this lower drying, by-passing `portions thereof through the ducts 72, and Vallowing to pass upward over the steaming :slaking lime 'sullicient :to volume for the currents to assist in thorough dissemination fof moisture at this stage and the preliminary mixing at the Y' sprays.

a relatively rotatable shaft in said shell with @outwardly extending divengling-zarms midway between ythe arms of :the shell, uniformly spaced platforms sustained by said shell and shaft arms providing annulardischarge ways at the overhanging remote ends of thewarms, and plows carried by the ,platform-sustaining arms fto coaot with material on the `relatively traveling platforms there- `below for progresswcontinuity in annularY Agravi-ty delivery between successive opposite radial travels.
